Device Story

Image-guided surgery system; uses electromagnetic tracking to locate surgical instruments relative to preoperative CT/MR/CBCT scans. System components: navigation unit, field generator (integrated into headrest), patient reference localizer (fixed to skull clamp), and tracked instruments (e.g., pointers, biopsy probes). Registration performed via fiducial markers, anatomical landmarks, or surface matching. Navigation unit generates electromagnetic field; localizer elements in instruments and patient reference localizer tracked within field. Real-time instrument position superimposed on preoperative images; updated at 15-45 Hz. Used in OR by surgeons. Provides visual guidance for precise anatomical localization; aids in surgical planning and execution. Field distortion detection mechanism monitors electromagnetic environment; excludes distorted values from display. Benefits include improved surgical accuracy and navigation for cranial procedures.

Clinical Evidence

Bench testing only. Evaluated positional and angular accuracy using coordinate measurement systems. Mean positional accuracy <2mm; mean angular accuracy <2°. Validated electromagnetic field distortion detection mechanism. No clinical data presented.

Technological Characteristics

### Device Description

The Fiagon Navigation System displays the position instruments in preoperative scans (e.g., CT, MRI, fluoroscopy) utilizing electromagnetic tracking technology. For cranial procedures, the use of this device is restricted to rigid fixation with a patient reference localizer attached directly to the skull clamp. The position of the instrument with integrated sensor and the patient referencing localizer (attached to the skull clamp) are localized within an electromagnetic field generated by a field generator. The principle of navigation is based on electromagnetic spatial measuring of localizer element in a generated electromagnetic field.

The display of navigation information requires an image-to-patient registration procedure. During registration procedure, the navigation system determines the coordinate transformation between the intraoperative position of the patient and the position of the preoperative scan by fiducial marker, anatomical landmark or surface matching.

Thereafter, the spatial position of the instrument is displayed superimposed to the image data. The navigation information is updated with a rate of 15 to 45 Hz.

The device Fiagon Navigation System utilizing similar technology than the proposed device has been previously cleared for a different intended use. This device is listed as a reference device.

| R1. | Fiagon Navigation System<br>Similar device, cleared for<br>different intended use | Fiagon GmbH | K133573 |

### Device Design

The components of the navigation system are

- 1. Navigation unit with Navigation software. It has interfaces for screen, mouse and the components 2 - 4.
- 2. Navigation sensor (Headrest with field generator)
- 3. Navigation instrument

4. Patient reference localizer (with fixation of the localizer on the skull clamp using the adhesive pad)

The navigation unit is connected to a medical monitor. The unit runs the navigation software. Preoperative radiological images of the patient (DICOM CT, CBCT, MR) is imported to the system by means of CD-ROM. USB storage media or LAN network and displayed in appropriate way (defined by the software).

The navigation unit compromises the spatial measuring device electronics as well. This has connections to the field generating device (navigation sensor), the patient reference localizer and the navigation instrument.

{5}------------------------------------------------

Patient reference localizer and navigation instrument are tracked within the generated field by localizer elements integrated in the devices.

The patient reference localizer is fixed to the skull clamp and references the patient's anatomy, while the instrument is tracked in relation to the patient reference localizer and thus to the patient's anatomy.

# 5. Intended Use

The Fiagon Navigation System is intended as an aid for precisely locating anatomical structures in either open or percutaneous neurosurgical procedures. The Fiagon Navigation System is indicated for any medical condition in which the use of stereotactic surgery may be appropriate, and where reference to a rigid anatomical structure in the field of cranial surgery can be identified relative to a CT or MR based model of the anatomy.

Example procedures include, but are not limited to:

Cranial Procedures:

- Craniotomies/Craniectomies (e.g., Tumor Resection) -
- Skull Base Procedures -
- Cranial Biopsies -
- -General Catheter Shunt Placement

# 6. Comparison of Technological Characteristics

The substantial equivalence of the Fiagon Navigation System to the predicates is shown by similarity in intended use, indications for use, materials, and performance. The Fiagon Navigation System and its predicates and the reference device utilize:

- Electromagnetic tracking technology for navigation in 2 cases and optical tracking in . 1 case. (For further details refer to the table below).
- . Anatomical or fiducial reference points on the patient's anatomy for intraoperative registration to the image-based model of the anatomy in 2 cases (Fiagon Navigation System and Stealth station system with synergy cranial Software) and Fiducial matching in the case of BrightMatter Navigation System V1.0).
- CT or MR image sets as reference images for the image-based model .

The primary difference between the Fiagon Navigation System and its two predicates is that the Fiagon System includes the option of navigating flexible-tip instruments by having the instrument localizer in the tip of the instrument. Since tracking a localizer in the tip of the instrument provides similar navigation accuracy as tracking the tip of a rigid instrument via a localizer mounted to the instrument handle, this difference does not raise new issues of safety and effectiveness.

#### 7. Performance Data

Testing was performed in order to determine device precision and accuracy and the electromagnetic field distortion detection mechanism. The following nonclinical tests were performed to determine substantial equivalence:

Bench testing was conducted to determine the device accuracy and the performance of the electromagnetic field distortion mechanism.

The tests performed to validate the accuracy of our navigation instruments ranged from validation of required accuracy (Positional accuracy and angular accuracy with registration) to measurement of technical accuracy with co-ordinate measurement system followed by measurement of positional and angular accuracy without registration to measure the angular accuracy of the instrument itself.

The non-clinical data support the safety of the device demonstrate that the Fiagon Navigation System perform as intended in the specified use conditions. The non-clinical data demonstrate that the device performs comparably to the predicate device for the same intended use.

# 8. Conclusion

Based on the indications for use, technological characteristics, performance testing, and comparison to the predicates, the Fiagon Navigation System has been shown to be substantially equivalent to the predicate devices identified in this submission, and does not present any new issues of safety or effectiveness.
